Patent number: 9376635Abstract: Systems and methods for extracting, handling and upgrading carbonaceous material. The systems and methods involve forming a reaction mixture of a carbonaceous material, a supercritical fluid, a catalyst and a source of hydrogen, and maintaining the reaction mixture at moderate temperatures for modest time periods. Exemplary reaction temperatures are those below 200° C. Exemplary reaction times range from 30 minutes to less than 24 hours.Type: GrantFiled: February 19, 2010Date of Patent: June 28, 2016Assignees: HSM Systems, Inc., University of New BrunswickInventors: Gerard Sean McGrady, Sarah Ann Brough, Christopher Willson

Patent number: 7931887Abstract: An apparatus and a method for controllably converting aluminum into alane. In the system of the invention, a reaction between aluminum and hydrogen to form alane is performed at temperatures below 100° C. using a supercritical fluid such as CO2 as a reaction medium, with the optional inclusion of a co-solvent, such as an ether, in the reaction vessel. Inert gas is used to exclude unwanted gases such as oxygen. The reaction of aluminum and hydrogen has been observed to proceed at approximately 60° C. using Me2O as an added solvent in CO2 at supercritical pressures.Type: GrantFiled: December 6, 2007Date of Patent: April 26, 2011Assignee: HSM Systems, Inc.Inventor: Gerard Sean McGrady

Publication number: 20110049016Abstract: The invention provides systems and methods for extracting and upgrading heavy hydrocarbons from substrates such as oil sands, oil shales, and tar sands in a unitary operation. The substrate bearing the hydrocarbon is brought into contact with a supercritical or near-supercritical fluid, a source of hydrogen such as hydrogen gas, and a catalyst. The materials are mixed and heated under elevated pressure. As a consequence of the elevated temperature and pressure, upgraded hydrocarbon-containing material is provided in a single or unitary operation. In some embodiments, sonication can be used to improve the upgrading process. Fluids suitable for use in the process include carbon dioxide, hexane, and water. It has been observed that upgrading can occur within periods of time of a few hours.Type: ApplicationFiled: June 11, 2008Publication date: March 3, 2011Applicants: HSM SYSTEMS, INC., University of New BrunswickInventors: Gerard Sean McGrady, Sarah Ann Brough, Christopher Willson

Publication number: 20090010836Abstract: The invention provides systems and methods for preparing hydrogen storage materials using low boiling point solvents or reaction media. Examples of such solvents or reaction media include dimethyl ether, ethyl methyl ether, epoxyethane, and trimethylamine. The synthesis of the hydrogen storage materials is conducted is a selected medium, and after synthesis is complete, the reaction medium is removed as necessary by moderate heating.Type: ApplicationFiled: June 20, 2008Publication date: January 8, 2009Applicant: HSM Systems, Inc.Inventors: Gerard Sean McGrady, Craig M.

Publication number: 20080213157Abstract: Systems and methods for producing ammonia. In one approach, Li3N is reacted with hydrogen to produce ammonia and is regenerated using nitrogen. Catalysts comprising selected transition metals or their nitrides can be used to promote the reactions. In another approach, supercritical anhydrous ammonia is used as a reaction medium to assist the reaction of hydrogen with nitrogen to produce ammonia, again promoted using catalysts.Type: ApplicationFiled: January 16, 2008Publication date: September 4, 2008Applicant: HSM Systems, Inc.Inventors: Gerard Sean McGrady, Christopher Willson
